After a terrible shipwreck in the Pacific, three survive - two children Emmelain Foster, Michael Reynolds and sailor Paddy Button. Not a long boat drift turned into luck in the form of a wonderful, uninhabited island. After ten years, in connection with the death of Paddy, the grown-up Emmeline and Michael remain alone.
With the help of ingenuity and cohesion, they continue to fight for survival against wildlife. On top of that, mutual love flares up.
